MIXING REQUIRED THIS IS THE CONCENTRATED VERSION!!!
Seems to let my truck keep its cool. I’ve used Peak in the past and it’s been of a good quality for keeping my vehicles happy overall. Pretty easy to mix especially if you happen to have an empty antifreeze jug and a measuring cup that you don’t want to use in the kitchen anymore. Or just go to the dollar store and get one that is at least 2 cups. 4 cups of concentrated coolant and 4 cups of distilled water into the empty container and give it a good shake then add 4 cups of distilled water to the container that was originally full then give it a good shaking! Now you have 2 gallons of 50/50 Dex-cool ready to go into your vehicle. 🚗You only need to add water if you purchase the concentrated coolant!IF YOU PURCHASE A 50/50 PRE-MIX DO NOT ADD WATER TO IT!! JUST POUR THE PRE-MIXED Coolant into your vehicle

Impressive coolant!!!
I bought this gallon of concentrate to top off my coolant system after a minor hose repair. The chemical makeup of this brand, PEAK, has worked wonders for my 2005 H2. My engines temps have decreased after having added this coolant.I chose a 50/50 ratio and turned the gallon of concentrate into 2 gallons of mixed. The color is orange and has a consistency that is a bit thick/thicker than other brands I have used.PEAK has all sorts of variations of coolant for all manufacturers. I am glad I chose the concentrate that is specifically for GM vehicles. Price wise, it is a great value when compared to 50/50 ratios.

Good stuff.
Fair price on Peak 100% antifreeze. Purchased it to make the minimum required for free shipping. Otherwise, it is a couple bucks cheaper at the local auto parts store. Not an Amazon junkie - came to buy a not-locally-available CD.

Antifreeze is all made to specific specifications
Well you know it's antifreeze it has to be made to a certain standard to get the Dex Cool name so it's all pretty much the same thing if it says deck school on the bottle
